Heera Bauri, councillor of 33 ward of Durgapur Municipal Corporation, and two others were arrested last night on the complaint lodged by Ritesh Trivedi, the director of the IT Hub at Durgapur.
Bauri assaulted Trivedi and others while they were bursting fireworks inside the hub premises on the occasion of Diwali, the police said.
The Trinamool leader, who organises a nearby Kalipuja, was unhappy with Trivedi as he did not get the subscription he had demanded from him, the police said.
Bauri was remanded to 14 days' judicial custody by a Durgapur court.
